The developers of Kingdom Come: Deliverance [Official Site, Kickstarter] have put out a Kickstarter update. The bad news is that the Linux version of Kingdom Come: Deliverance will not be a day-1 release.
This was quite obvious from their lack of communication about the Linux version, but it's still sad to see it written up now.
I have to hand it to the guys working on Albion Online, they certainly are putting the effort in to polish the game up for a big release. The big 'Faye' update has landed and it's huge.
Note: I still suggest waiting until the beta ends, since players will be wiped.
Toward the end of November was a discussion that started about potentially dropping all of the FBDEV Linux kernel drivers that are currently in the staging area, but it doesn't look like that will go through, at least until the relevant hardware has seen basic DRM driver ports.
Games company Feral Interactive’s call for a PPA be set up to offer the latest Stable Mesa drivers on Ubuntu has been semi-answered. Emphasis on semi, there. As noted by Gaming on Linux, a new stable Mesa PPA is now available — hurrah — but it is not “official” in the way that the stress-tested Nvidia drivers PPA is — boo.
Feral Interactive's call for a stable Mesa PPA has already made progress, as there's now a stable PPA available for Mesa.
Paulo Dias "Padoka" has setup another PPA here: https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa
Note: This is a community-run PPA, so it's possible it may someday go out of date and/or have issues at times.
This is likely a stop-gap measure until something more official is done.
It currently hosts Mesa 13.0.2 and LLVM 3.9 along with RADV and ANV the AMD and Intel open source Vulkan drivers.
